Too bad you used Lexan. It fogs up completely in three years, and after that , you wont be seeing much thru it. That will give you your privacy back.
True in general, but perhaps not as bad as stated....
Our original fixed ports were Lexan. Badly "fogged" when we replaced them in '95. The first owner had never (!) taken care of them at all.
Deciding that there was no reason to doubt the original engineering specs, we replaced with Lexan, even knowing it's reputation for hazing.
BTW, there are surface coatings/layers nowadays commonly applied to Lexan that much reduce the hazing.
(We needed to properly rebed all the lenses anyway, due to leaks un-addressed by the prior owner.)
Anyhow, to make a long story slightly shorter, we installed them with the proper sealant, at the proper depth, and they are still clear... and... leak free.
That is, clear for about two months at a time after I polish them out and overcoat/buff them with Plexus
So, they will indeed get hazed up if neglected, but the neglect is not required.
ps: note that even smoked Lexan (or acrylic) - with some hazing - will be disturbingly transparent from the outside at night to passers-by on the dock...... even though you cannot see out from the inside of a lighted interior.
pps: CCHER, Nice Looking carpentry!!
